Scattering theory of frequency-entangled biphoton states facilitated by cavity polaritons
Andrei Piryatinski, Nishaant Jacobus, Sameer Dambal +3
The use of quantum light to probe exciton properties in semiconductor and molecular nanostructures typically occurs in the low-intensity regime. A substantial enhancement of excito…

Topology and Spectral Entanglement in Cavity-Mediated Photon Scattering
Eric R. Bittner, Andrei Piryatinski
We develop a diagrammatic theory of cavity-mediated photon-photon interactions in a topological insulator using the SSH model. The fourth-order vertex governs sp…

Tensorial Spin-Phonon Relaxation Reveals Mode-Selective Relaxation Pathways in a Single-Molecule Magnet
Roman Dmitriev, Nosheen Younas, Yu Zhang +2
Understanding and controlling spin relaxation in molecular qubits is essential for developing chemically tunable quantum information platforms. We present a fully first-principles…
